“…Therefore, developing photocatalysts with desirable selectivity to transformation and purification of targeted pollutants is of great importance in water purification [17][18][19][20]. Recently, several researchers have shown that selective photocatalysis can be approached by modifying the surface of the photocatalysts with specific molecules [16,[21][22][23]. Therefore, a shell with molecular selectivity around TiO2, which combines the merits of the high photocatalytic activity of TiO2 and the photocatalytic selectivity of the surface modifiers, would be used as a highly selective photocatalyst.…”

Photocatalysts with desirable selectivity to transformation and purification of targeted pollutants are of great importance in water purification. Here, we demonstrate that selective photocatalysis can be realized by the assistance of gold-enhanced selective adsorption onto carbon-coated Au/TiO2 mesoporous microspheres (Au/TiO2@C-MM), which were prepared via a surfactant-assisted two-step method that involved the assembly of oleic acid-stabilized titania and gold nanoparticles into colloidal spheres in an emulsion using sodium dodecyl sulfate as a surfactant and the conversion of the surfactants into carbon under annealing in Ar. Due to the negatively charged amorphous carbon, the mesoporous structure, and the surface plasmon resonance absorption of the Au components, the Au/TiO2@C-MM shows enhanced charge-and size-selective adsorption properties, which enables the materials to have high selectivity in the photocatalytic process.

“…Even if much progress has been reported in recent years, there is still a relatively long way to go using the classical way of making imprints towards transition-state analogues of the substrate to be converted. An alternative route has been taken by coimmobilizing the MIP and a photocatalytically active unit, for example, titanium dioxide [43,44].…”

Molecularly Imprinted Polymers in Biotechnology

Molecular imprints are potentially fantastic constructions. They are selective, robust, and nonbiodegradable if produced from stable polymers. A range of different applications has been presented, everything from separation of enantiomers, via adsorbents for sample preparation before analysis to applications in wastewater treatment. This chapter deals with molecularly imprinted polymers (MIPs) as tools in environmental biotechnology, a field that has the potential to become very important in the future.

“…Many approaches have been proposed to develop active and stable photocatalysts, including doping TiO 2 with metal ions or metal atoms, incorporating nitrogen and carbon into TiO 2 , and employing other non-TiO 2 metal oxides as photocatalysts [15][16][17][18][19][20][21][22][23][24]. Non-TiO 2 photocatalysts have attracted a great deal of attentions because of their high photocatalytic efficiency and potential application in environmental remediation [25][26][27][28][29].…”
